Node 18 is going EOL

[cjihrig]

Node 18 is going EOL tomorrow (April 30). How do we want to handle that? Do we want to immediately drop support for it, or continue supporting it for some time? If we want to continue supporting it - for how long? If we want to drop it immediately, many people advocate for dropping support being a semver major change.

As a consumer of this package I personally wouldn't expect support for node 18 beyond it's EOL date. Anyone still using node v18 in production after April 30, probably won't be giving priority to patching dependencies anyway. At least their priority should be to get onto the next LTS of node at that point.

@cjihrig PS. what's the process for getting a new release cut? I'm waiting to test something out which needs this fix that was recently merged: #2367

That's definitely the preferable attitude IMO 😄. But, the truth is that there are a lot of people that don't feel that way. There are even companies that offer commercial support for EOL versions. For the purposes of this library, the question is just whether or not to do a major version bump when dropping old versions.

what's the process for getting a new release cut?

I think @brendandburns is the only person that can cut a new release, but I could be mistaken.

[brendandburns]

Actually anyone with github actions privileges on the repo (should be all maintainers?) can cut a release.

@rossanthony we typically cut a release for each new Kubernetes release. If there is an issue that is majorly impacting we can cut a patch release. How urgent is this fix for you?

[rossanthony]

@brendandburns it's not super urgent, isn't impacting us in production. But we're trying to build a solution for sharing auth tokens via k8s secrets, leveraging the informer in this library. We previously had it in beta and noticed it was hammering the kube API, because of that socket timeout issue.

Looks like the latest kubernetes release is 1.33 (https://kubernetes.io/releases/) released: 2025-04-23, but the last release of this package was 1.1.2 3 weeks ago.

[brendandburns]

@rossanthony yeah, we need to regenerate the client and cut a new release. Probably 2-3 weeks I would guess (maybe faster)

TIL. I'd be happy to help out with this. Is the release process documented anywhere?

Hi @brendandburns ,

We're in the process of preparing a new release based on version 1.1.2, but we're currently blocked by the socket timeout issue on AKS clusters. Unfortunately, this fix was not included in the latest release: #2367.

This issue is becoming critical for us. Would it be possible to cut a new version early next week to help us move forward without further delays?

We’d greatly appreciate your support on this.

For more details:

i coded a basic example where we can reproduce the error:

// index.js
import * as k8s from '@kubernetes/client-node';

export async function getConnection() {
    try {
      const kc = new k8s.KubeConfig();
  
      kc.loadFromDefault();
  
      const opts  = {};
  
      await kc.applyToHTTPSOptions(opts);
  
      return { kc, opts };
    } catch (err) {
      throw err;
    }
}

export async function observe(
  plural,
  namespace,
) {

  const { kc } = await getConnection();

  try {

    const k8sApi = kc.makeApiClient(k8s.CustomObjectsApi);

    const apiGroup = 'test.dev';

    const apiVersion = 'v1';

    const apiPaths = `/apis/${apiGroup}/${apiVersion}/namespaces/${namespace}/${plural}`;

    const listFn = () => {
      return k8sApi.listNamespacedCustomObject({
        group: apiGroup,
        version: apiVersion,
        namespace,
        plural,
      });
    };

    const informer = k8s.makeInformer(kc, apiPaths, listFn);

    informer.on('add', (obj) => {console.log("on add")});

    informer.on('update', (obj) => {console.log("on update")});

    informer.on('delete',(obj) => {console.log(`on delete`)});

    informer.on(
      'error',
      (err) => {
        console.log("kind", plural);

        const time = new Date();
        console.log(time.toJSON())
        console.log('informer (on error): ERROR %O', err);
        process.exit(1);
      }
    );

    const time = new Date();
    console.log(time.toJSON());
    informer.start();

  } catch (err) {

    throw `Observing: ${plural}: ${err}`;
  }
}

for(const plural of [
    'testplural-1', 
    'testplural-2', 
    'testplural-3', 
    'testplural-4']) {
  observe(plural, 'firestartr-github')
}
